∙ 10y agoGoing down and to the left on the Periodic Table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.

∙ 11y agoIt tends to increase
The atomic radius increases down the group
Wiki User
∙ 11y agoThe atomic radius increases on going from the top to the bottom of a group as the number of shells (energy levels) increases.
Wiki User
∙ 14y agoThe lower down on the periodic table the higher the energy level, making the atomic radius larger
Wiki User
∙ 12y agoAtomic radius increases with increasing period number (= going down) within the same group.

Answer #2:
It decreases.
It tends to increaseThe atomic radius increases down the group
The atomic radius decreases.
The atomic radius decreases.
atomic radius decreases from bottom to top of the periodic table.
Along a period, nuclear charge increases. hence, atomic radius decreases.
It tends to increaseThe atomic radius increases down the group
The atomic radius decreases.
The atomic radius decreases.
atomic radius decreases from bottom to top of the periodic table.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
Examples for the groups I an II of the periodic table:- the atomic radius grows from top to bottom- the electronegativity descends from top to bottom
Yes, francium has the largest atomic radius of any element on the periodic table. This is due to its position at the bottom of the alkali metal group, with only one valence electron and a high number of energy levels, resulting in a larger atomic size.
the larger the highest energy level number, the larger the atomic radius (Apex)
Down a group, the atomic radius increases as the number of shells or energy levels increases.
The larger the highest energy level, the larger the atomic radius.
